This card sells for very little, so its price is Cardmarket's monthly trend, not a median of completed sales. It can be a few cents off: treat it as an indication, not a precise number.
If you add this card to your portfolio, it won't be counted toward your total portfolio value. It's here so collectors can still track their collection's progress, without inflating the total with low-confidence prices.
